DETAILED DESCRIPTION
[0020] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.
[0021] like Figure 1-Figure 4As shown, the negative pressure self-cleaning water collection cross-cutting ditch device includes an integrated cross-cutting ditch 1, which is buried in the road surface and has a water flow sensor 2 on the top;
[0022] Equipment rooms 3 are respectively arranged on both sides of the length direction of the integrated cross-sectional trench 1, and a motor 4 is arranged in the equipment room 3. The output end of the motor 4 is respectively connected to an exhaust pipe 5, an air extraction pipe 6, a water extraction pipe 7 and a high-pressure water gun 9. Electric valves 10 are respectively arranged on the exhaust pipe 5, the air extraction pipe 6, the water extraction pipe 7 and the high-pressure water gun 9. The high-pressure water gun 9 extends into the integrated cross-sectional trench 1;
[0023] The air extraction pipe 6 and the water extraction pipe 7 extend into the water reservoir 11 respectively. The air extraction pipe 6 extends to the top of the water reservoir 11 , and the water extraction pipe 7 extends to the bottom of the water reservoir 11 . The water reservoir 11 is connected to the integrated cross-sectional ditch 1 through the drain pipe 8 .
[0024] A control box 12 and a power supply system are provided in the equipment room 3. The control box 12 controls the working status of the motor 4 and each electric valve 10 according to the data received from the water flow sensor 2. The power supply system is used to supply power to the water flow sensor 2, the motor 4, each electric valve 10 and the control box 12.
[0025] The main innovation of the present invention is that the integrated cross-sectional ditch ensures the overall rigidity and strength, and improves driving safety and comfort; the silt in the pipeline of the integrated cross-sectional ditch can be automatically cleaned after rain or regularly, without manual dredging, reducing traffic impact and maintenance costs.
[0026] The control box 12, the water flow sensor 2, the electric valve 10 and the power supply system constitute an automatic sensing control system. When the water flow sensor 2 detects that rainwater flows into the integrated cross-sectional ditch 1 on the road surface, the negative pressure vacuum device is started, and the negative pressure intensity can be automatically adjusted according to the water flow rate. After the water flow stops, the electric valve 10 of the air extraction pipeline 6 and the exhaust pipeline 5 is closed, and then the high-pressure flushing device is started, and the electric valve 10 of the water extraction pipeline 7 and the high-pressure water gun 9 is opened to extract rainwater in the water reservoir 11 to flush the inner wall of the pipeline 101 of the integrated cross-sectional ditch 1.
[0027] The motor 4, the air extraction pipeline 6, and the exhaust pipeline 5 form a negative pressure vacuum device. When the water flow sensor 2 detects the water flow, the negative pressure vacuum device is started, and the electric valves 10 of the air extraction pipeline 6 and the exhaust pipeline 5 are opened. The gas in the water reservoir and the cross-cutting ditch is discharged through the device to form a negative pressure state, thereby accelerating the drainage capacity of the integrated cross-cutting ditch 1.
[0028] The motor 4 (shared with the negative pressure vacuum device), the water-drawing pipe 7, and the high-pressure water gun 9 constitute a high-pressure shower device. After rain or regularly starting, the rainwater after precipitation in the water storage tank 11 is drawn, and the high-pressure water gun 6 washes the inner wall of the pipe 101 to automatically clean the sludge in the pipe 101.
[0029] Furthermore, the integrated cross-sectional ditch 1 includes a pipeline 101 buried under the road surface, and a water collection port 102 is opened along the length direction of the pipeline 101 at a position of the road surface corresponding to the pipeline 101, and the water collection port 102 is connected to the top of the pipeline 101. The pipeline 101 is made of D400 stainless steel pipe, and is externally encapsulated with 15-20cm thick UHPC ultra-high performance concrete, and the bottom is T-shaped. A 10cm gravel cushion layer is set for leveling. The integrated cross-sectional ditch 1 also includes concrete 103 and a cushion layer 104.
[0030] like Figure 5 As shown, the working principle of the present invention is:
[0031] After the control box 12 starts the calibration, it detects whether there is water flow according to the detection of the water flow sensor 2;
[0032] If there is water flow, the control box 12 automatically controls the electric valve 10 of the water-drawing pipe 7 and the high-pressure water gun 9 to open, and the motor 4 starts to rotate forward, so that the cavity of the integrated cross-sectional groove 1 forms a negative pressure, and the water flows into the integrated cross-sectional groove 1 and is discharged into the water reservoir 11. The water flow sensor 2 continues to check whether there is water flow. If there is still water flow, the above operation process is repeated; if there is no water flow, the control box 12 controls the electric valve 10 of the exhaust pipe 5 and the exhaust pipe 6 to open, and the motor 4 starts to reverse, sucking the water in the water reservoir 11, and the high-pressure water gun 9 flushes the pipe 101, and the operation is finished;
[0033] If there is no water flow, the next step is performed according to whether the water flow sensor 2 is set with a detection interval. If the interval is set, the control box 12 controls the electric valve 10 of the exhaust pipe 5 and the exhaust pipe 6 to open, the motor 4 starts to reverse, the water in the water reservoir 11 is sucked, and the high-pressure water gun 9 flushes the pipe 101; if the interval is not set, the operation is terminated.
[0034] In summary, the present invention adopts automated negative pressure vacuum equipment and an integrated cross-sectional ditch 1. The negative pressure vacuum equipment can increase the drainage capacity of the integrated cross-sectional ditch 1. The road surface only needs to be provided with a single-seam water collection outlet 102 to meet the drainage requirements. The integrated cross-sectional ditch 1 adopts an integrated structure to ensure the overall rigidity and strength, and improve driving safety and comfort.
[0035] The present invention adopts an automated high-pressure flushing device, which can automatically start cleaning the silt in the pipeline 101 after rain or regularly, without the need for manual silt removal, thereby reducing traffic impact and maintenance costs.
[0036] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
